Review on Munchkin True HEPA Air Filter Replacement For Air Purifier, 3 Pack by Alisa Romero

I was looking for a small, easily portable air filtration system with true HEPA to add protection at jazz clubs. This device is the size of a tall soda can, very light, and is almost totally silent on the low setting. I've placed it in front of me at a few jazz concerts in the short time I've had it, and it made me feel a bit more protected while not interfering at all with the music. It's small and certainly won't clean the whole room, but if it can unobtrusively purify the air right around me, it would add a reassuring margin of safety to my mask-wearing. Very very very quiet on the lowest setting - you really don't hear it! The higher settings are noisier and not for music venues, but when I resume air travel, this'll be on my tray table.
